Preliminary data based on the notification from the South African authorities:
The aircraft was engaged in non-scheduled domestic flight from FACT to FAGM. During a descending turn from base to final runway 17, the PIC increased bank angle to avoid an overshoot, and the right wing impacted the top of a tall tree(This is an assumption based on the damage sustained, as no impact force was experienced). While correcting for cross-wind drift before touch down, the left wingtip scraped the runway. the damage to both wingtips was only discovered after aircraft shut down. The damage to the aircraft entails the replacement of the slats, ailerons and wingtips on both wings.
